If you are absolutely sure there is no 1095A lurking out there ( I would have client check at healthcare.gov) then you can give IRS what they want ( I had a couple of them) Just fill out a 1095A with your state in box 1, and 123456 in box 2, and $1.00 in 21A. Worked for me, and one of the clients got his refund with no problems.
