Turbotax Business. The problem was form 8453. I followed the instructions to the letter. I printed it, signed it and saved it as a PDF but it did not "go through". I tried many times. In the end I deleted the form then went through the 5 steps to recreate the form and attached it NOT filled out. The program created a form with a filename. Now close Turbotax.
I printed 8453 and signed it. I saved it as a PDF. I made note of the filename and it's location then I deleted it. I renamed MY file using the computer generated file name and put it in the original folder. I opened Turbotax and refiled and it went through.
I am convinced you must use the filename the program created and put it in the program folder.
