Get your taxes done using TurboTax

I have always had to mail in my parents tax return, so there is no prior e-file with Turbo Tax.  This year is the first year my Mom is filing as a widow.  I have looked into the 2019 Turbo Tax file, and because they did not e-file, there is no record of a self-select pin (or I cant seem to get back to it if there is).  The AGI is correct, but the return has been rejected 3 times.  Any ideas?
