Business & farm

Two comments and a request for help:

1) It is an error on TT that it allows you to efile Federally if it already told you have to attach form 8990.
(As someone else said, you could blank K-1 line 13 if you don't want to take the future credit and efile)
2) Suggestion to TurboTax if they don't want to support Form 8990:
At least have the form available for the user to filll it in and still be able to efile.

 

This is my first year of 8990 and it means that I have to manually file until I use up the deferred "Excess Business Interest" credit carryover. 

 

Question: In a future year when I can use the excess business interest to offset K-1 excess business interest income, how does that tie back to the main return (K-1, schedule E, 1040) to take advantage of the prior carryover?

Thanks in advance.
