There is another post string specific to the Error 54 problem this year and so far Turbotax has only given suggestions that do not work. There are a lot of us in the same boat and not able to efile our 1041s.
Hopefully enough people will post to get Turbotax's attention (hint, hint...) and they will fix this before we all need to go buy a different product to efile our returns.
