this seems to be a recurring issue with Turbotax. Since I can't see the actual 1099-B I don't really know if there really was a .20 wash sale. some things you can try but no assurances they'll work. 1) delete the import. close the return. open the return re-import. 2) round the sales price and cost to whole dollars and delete wash sale amount. 3) contact support.
if you find something that works please post back so others can be informed.
