1099-B wash sale entry triggering a review prompt in TT. Do I ignore the prompt or have to remove the wash sale amount?

For example,

1099-B states:

Proceeds: $4900
Cost Basis: $5500
Wash Sale Loss Disallowed: $250
Gain or Loss(-) : -350

The file import of my broker's 1099-B correctly filled out these areas in TT; however later on it gets flagged to check the entry, saying:

"Form 1099-B Worksheet (TD Ameritrade) : Wash sale loss disallowed is only for wash sales. Do not enter for I Shares Silver Trust ETF"

I'm very confused by this. Any help would be greatly appreciated.
