Struggling with similar scenario.
TT import of Fidelity takes Wash Info from Supplemental Info -- not from 1099-B.
While it prompts for Adjusted Basis (correct 1099-B), it does NOT prompt to correct Wash Sale Disallow from 1099-B.
It also contradicts itself in asking to verify "exact" match to 1099, while failing to import the 1099-B wash sale data (and rather taking it from the supplemental information).
Assuming it's a TT BUG. Might drop TT after so many years.
