Problem still has not gone away on returns that I already had prepared with MW codes. Was the Form 8453 supposed to all of a sudden go away under this fix you mention? Not happening.

Also for several returns I have done in the last few days I also get a blank Form 8453 whenever I have use code M for an attached PDF file and a code B or E is used indicating basis not reported to IRS. I think your programmers need to take another look at the problem.
