I am having the same issue. TT states that my return has certain forms that can't be e-filed because of tax regulations, and that I will also have to file my state (CA) return by mail. I have a very simple return, I've reviewed it all and have nothing new from last year. I checked what forms the IRS is requiring to be filed by mail, and I have none of those either. Hoping you are able to provide some updates/answers.
Thank you !
