It's difficult for folks in a user community to help you in a public Internet forum like this because you are the only one who can see your returns. If you prepared two 2020 returns in different accounts, you'd need to print out the return from each account and compare them line by line to know what to follow up on to see where the discrepancy is. If the end result on the Form 1040 (the net tax due or refund) is different on the 2 returns, there are bound to be other lines higher up on the Form 1040 that are also different. Those lines will give you a clue as to what topic to investigate. Sometimes it can be as simple as someone putting a decimal or a comma in the wrong place, or mistyping and reversing some digits. And answering a "Yes or no" question differently on an interview screen can often cause significant changes.
