I had the same problem and TTax Support couldn't put their finger on it. So, I went to the IRS website and verified that certain finalized forms had simply not been released yet. My program knew that some of the forms were not finalized, but the TTax update routine apparently had a bug in it, and kept saying everything was current and there was nothing to download. The IRS finally released the updated forms, TTax business now updates properly, and I just completed and successfully e-filed a 1041 return.
