Will turbo tax automatically handle cross brokage, cross year, washsale between 2 tickers?(but it's the same company)

[cats881119]

In 2020 I sold some RDS.A shares and bought RDS.B shares in robinhood. Since both tickers belong to the same company, in the 1099B from RH, it was classified as wash sale loss disallowed .

In 2021, I transferred my RDS.B (and a few other positions) positions to IB, the cost basis IB got from robinhood is unadjusted, meaning the wash sales loss is not added to the cost basis of those RDS.B shares.

My question is, If I sell those RDS.B position in 2021, will turbo tax adjust the cost basis while reporting my tax in 2021(like properly utlizing the previous washsale loss)? I am little concerned since this is cross brokage, cross year and between 2 different tickers.   If turbotax cant handle it automatically, what will be my best approach? (I hope it will not be too tedious)

Thank you very much for you input!

TurboTax won't do that for you.

Neither will your brokerage firm.

Brokers don't exchange information on what you are up to at the other brokerage.
