I've got a new client who set up their partnership in December 2019. They haven't generated any revenue yet, but they've had expenses in both 2019 and 2020, so we need to file back returns. Page 2, question 4c is "no" (Schedules K-1 are filed with the return and furnished to the partners on or before the due date (including extensions) for the partnership return). But if I check "no", it gives me a red error. The only way to fix it is to check yes. What am I missing? Thanks!
