If you used the online version last year and need to transfer your info to this year's Desktop version there are 2 ways depending on what you have.
1. If you saved the actual .tax2019 file (not just the pdf file) to your computer before online was shut down in Oct. then start a new return and the very first thing you do is Transfer from .tax file. You can only transfer at the very beginning. You should be able to download the .tax2019 file from online, like if you were going to amend.
2. If you didn't save the .tax file to your computer or lost it, there is a way to do it by starting a 2020 return in the Online version, transfer to that and then continue in the desktop version. You won't have to pay for Online.
