When will you fix the Michigan form 4884? It is not working correctly - gives the wrong answers. I spent many hours trying to figure out what was wrong: (1) The form does not link to the correct places on the Michigan 1040; (2) The form does not pick up the correct information from the Federal 1040 and (3) the final "error correction" process (prior to filing) does not pick up these problems. I discovered (and used) the Michigan tax site estimator for retirement benefit exclusions, and it gave me an answer close my final (spreadsheet) calculated amount (after studying the Michigan form 4884 instructions in detail) - this was my first confirming evidence that the turbo tax Michigan form 4884 was way off.
