What I found out last year was that all the K1s I had diligently entered did not actually get calculated into my tax return. Per Turbotax, ONLY DESKTOP is even set up to incorporate K1 entered info. Also, even if you're using Desktop, it's really not good at carrying over the information properly to your next year's return. After many years of TT, I had someone do my taxes last year.
Also, the TT option to have them do full service was twice as expensive as a regular tax acountant, and TT will not review previous tax returns. Even the TT rep suggested not using them. K1s are too complex.
