Thank you so much for this workaround, @Deborahwrites1. I finally got this to work once I read your update that after going to Forms, you then need to click the Open Form button/icon and do a search for 7206. When I first tried to delete any additional form 7206s I was just scanning down the list of forms in my return and only seeing the one related to my Schedule C for the deduction of non-Healthcare Exchange premiums. When I searched for 7206 I got results for my Schedule C and for some reason each of the Schedule K-1s in my return. I opened all of the form 7206s for each of the 5 K-1s and deleted them all.
NOTE: Even after deleting and saving the return (there was no change in TT's calculated taxes) they still do show up in a search for 7206, but if you click on them TT prompts you to add a form. I took this to be a bug of some kind and took it on faith that even though they appeared in search results, they really had been deleted. I refiled the Federal return and it was accepted finally (3rd attempt) and once I got the confirmation that the return had been accepted I refiled my State return.
Again, THANK YOU SO MUCH for figuring out the workaround! I am so glad that I didn't have to file a paper return.
