Welcome to Canada!
As a first time tax filer, you will have to mail your return in by paper as they have no records for you yet. This is also why you could not create an account with CRA. You will enter the date of entry when you say yes to residency change in the interview section.
Since you show a preference for the download version, I would recommend the Home and business download. It is good to use for new residents and great for your self-employed income. It can handle the overseas investments as well.
DTC and medical are included in all versions of turbo tax.
You can also add "Pro Review" to the product and it includes all the returns prepared using the downloaded software. One price to review all the returns. I highly recommend this service since this is your first time preparing and you have overseas income to report. You may even speak to me. 🙂
