TT has never been able to provide me with enough lines. What I have had to do every year is download the fillable PDF from CRA, complete this fillable form manually (which is essentially all you do with TT), print the fillable-PDF off, sign the printed CRA-original (not TT) form, mail it through Canada post and hope it makes it. Unfortunately I purchased TT-2023 desktop, and my workaround this year was to subsequently buy a competitor's 2023 software (which allowed me to enter all 8 lines in section 2) and I will it to submit my T1 & T1135 this year.
What has been frustrating is that TT was not transparent with this limitation. They indicate you can use the product to submit a T1135, but don't indicate that their desktop version has this limitation. Have provided this as feedback every year. Nothing but crickets.
I am comfortable with desktop certified software as it keeps all sensitive information on my PC and not in a central DB (will no use on-line).
