If both LLCs are disregarded entities (which presumes you did not make an election for each LLC to be treated as an S corporation for federal income tax purposes and there are no other members), you should not have received a K-1.

Income and expenses from disregarded entities are typically reported on Schedule C (Form 1040).

If this is a partnership that issued a K-1 form an you have entries in both box 1 & 2  then here is the data entry trick ...

Enter the K-1 and enter everything on it  EXCEPT the box 2 amount ... then enter in another K-1 and this time ONLY enter the box 2 amount.  The program will automatically merge them.
