Hard to tell what the software will do this year.
In some prior years, the software created an entirely new form when you imported the same document from the same financial provider a second time. (Like, importing a 1099-INT from the same bank twice)
Then a year or two ago they started overwriting the prior form.....IF..it was the same form type...;;...from the same provider. But they may have changed that and it's too soon to tell.
Certainly, if you do get duplicates forms from re-importing, you can always delete the duplicate....just practice navigating around in the software early in the season so you can see how it would be accomplished.
