There's an error in the Quebec Solidarity section. The question "Do you live in dwelling either alone or with one or more people" should read "ONLY one or more people..."

Here are the eligibility requirements - Hope this helps clarify. Which can be found on the blue eligibility link on the Solidarity Tax Credit form in the Provincial tab, after you have completed the Profile Section of your return.

You can claim the solidarity tax credit for the payment period from July 1, 2019, to June 30, 2020 if, on December 31 2018, you meet all of the following requirements: 

• You are 18 years of age or older or, if you are younger than 18, you 
  
  • have a spouse;
  • are the father or mother of a child who lives with you; or
  • are recognized as an emancipated minor by a competent authority (such as a court).
• You are resident in Québec.
• You or your spouse is 
  
  • a Canadian citizen;
  • a permanent resident or a protected person, within the meaning of the Immigration and Refugee Protection Act; or
  • a temporary resident or the holder of a temporary resident permit within the meaning of the Immigration and Refugee Protection Act, who has been living in Canada for the preceding 18 months.

However, you are not eligible for the solidarity tax credit 

• for the month(s) at the beginning of which you are confined to a prison or similar institution on December 31, 2018, and, in 2018, you were confined for one or more periods totaling more than 183 days; or
• for the month(s) in which someone receives the child assistance payment from the Régie des Rentes du Québec with regard to you.

A dwelling (for example, a house, a room or an apartment in a duplex or condominium building) located in Québec in which an individual ordinarily lives and that is the individual’s principal residence, excluding, for example,

• a dwelling in low-rental housing within the meaning of the Civil Code of Québec that is an HLM or a dwelling for which the Société d’habitation du Québec agrees to pay an amount towards the rent;
• a dwelling in a facility maintained by a public institution or private institution under agreement (publicly funded) that operates a hospital center, a residential and long-term care center (CHSLD) or a rehabilitation center governed by the Act respecting health services and social services;
• a dwelling located in a hospital center or reception center within the meaning of the Act respecting health services and social services for Cree Native persons;
• a dwelling for which an amount is paid toward rent under a program governed by the National Housing Act (for example, a dwelling located in a housing cooperative);
• a dwelling located in a building or residential facility where the services of an intermediate resource or a family-type resource are offered;
• a room located in the principal residence of the landlord where fewer than three rooms are rented or offered for rent unless the room has either a separate entrance from the outside or sanitary facilities separate from those used by the landlord;
• a room located in a hotel establishment or in a rooming house that is leased or subleased for a period of fewer than 60 consecutive days.

Thanks I found this. What I'm pointing out is an error in the interview under "provincial" and "solidarity tax credit" that you might want to fix to avoid confusion.
The word "only" is missing under:
"Throughout 2018, did you live in a dwelling either alone or with ONLY one or more people under 18?"
 It causes confusion and an error as presently worded. Thank you.

Duly noted.  Thank you!

On TurboTax 2020, the explanation on The EasyStep is:

(You are considered to have lived alone if you lived with only one or more people under 18.)

But I think the original explanation, from the Quebec Schedule D, is clearer:

(You are considered to have lived alone if everyone that you lived with was under 18.)

So, in my humble opinion, we should use the less confusing one.
