Troubleshooting

I don't want to print my returns not sure why that was posted. 

 

What I want to do is modify my 2019, 2020 and 2021 returns I filed using Turbo Tax.  All I see is pdf files so I cant refile.  Someone said to login into CRA and change the forms.  Well this is very difficult as I don't know what to change.

I've tried but its incredibly difficult.  I'm trying to change the following and have no idea where on a 72 page return what lines I need to amend:

1.  Designated Disability Transfer from one parent to another.

2.  Claim the GST for employer expenses and provide employer GST number.

3.  For disabled dependent

Did the dependant live with you in 2022?
 
Was the dependant mentally or physically infirm?
 
If the dependant was mentally or physically infirm describe the nature of infirmity
 
Does Olivia depend on others for assistance in personal care because of a prolonged and indefinite physical or mental impairment?
 
 
Do you have a signed statement from a medical doctor?
