Thanks for your answer, David.
Based on your reply I see I didn't explain myself correctly. The reason for thinking about using TT Desktop was to be able to input the combined taxes resulting from my multiple 8621s into my tax return. As indicated by a fellow expert of the community, the way of working is the following:
"Go to 1040/1040 SR WKS Go to Schedule 2 Part 2 Line 17Q Here is where you will report the taxes that were generated on Form 8621. Here you will combine the totals from both 8621's".
The alternative that was mentioned was to fill in may 8621s and send them together with my return and a note explaining TT online would not let me input this info.
So, based on this info, if I were to use TT Desktop, which version shoul I acquire?
