I had this same problem and found a fix after multiple submissions to the IRS. I had two 7206 forms -- one under a Schedule C and another under K-1. I went to the forms view and tried to delete both of them because they were not needed. It let me delete the 7206 form for the Schedule C. When I tried to delete the 7206 form for the K-1, it never went away. I then went into the 7206 form under the K-1 and manually entered zeroes for the fields that were blank. I filed my return again and just received confirmation that it was accepted. Unfortunately, it is April 16th, so I need to explain to the IRS that it wasn't my fault that it was submitted a day late.
