This may have been discussed already, but I didn't see it on the search function.  As of today, 3-25-2022, when importing K-1 information into a 1040, not all the information pulls into the form 7203.  Mainly the line 3a, ordinary business income has to be manually entered for the basis to have the correct ending basis.

Maybe this will be updated later, but always make sure imported numbers go to the correct place!
