Turbotax Premier has the same issue with Oklahoma form 561NR in their 2020 desktop program. It is a bizarre problem, since in the STEP by STEP version you must use: "Edit" on the "Summary of Oklahoma Capital Gains and Losses" screen (even though they may have nothing to do with Oklahoma if your capital gain or loss was from another state). On the Edit screen there is a check box that states "This property does not qualify for exclusion." ..........THIS IS WRONG! IT SHOULD SAY This property does qualify for exclusion. Because if you check it on the Form View, then this issue gets resolved, but then you are only half way there. Because after all of these gyrations, you still have to deal with the Date of the capital gain sales transaction, even though I had indicated $0 entry for Oklahoma portion. This pops after running the error check one more time. To resolve the sales date issue, I entered 12/31/2020, reran error check, came back to the same location, deleted the date, reran the error check and this time it worked. This year I have had considerable issues with both Turbotax Business and Premier. Transferring information from Business to Premier via Sch K-1, was not fun at all.
