@taxnovice You describe correctly what TT does wrong. Your educated guess as to how this part of its software works internally is feasible - but neither I, nor anyone else on this forum [1] know for sure, or [2] give a **bleep** about its internal workings. Simply put, TurboTax is wrong when it erases all my previous imported data.
IT
SHOULD
NOT
DO
THAT.
And the TurboTax personnel are wrong to ignore this bug, refuse to fix it and refuse to communicate with us on this topic. Extremely disappointing.
