Same here. I just noticed the problem on this year's return, TT did not carry over after tax contributions from 2014, and 15, and 16 into form 8606 in the following year's filings. For my 2017 filing I've had to force the total basis number to include prior years, and wrote an explanatory note citing this TT bug. How do we notify TT of the issue and get them to fix it?
