which version off TT is this, desktop or online? Deleting Box 10 or setting to zero usually clears the issue. EasyStep doesn't reject the 1099-OID entry to begin with, and it just shows as an error in Forms mode in desktop. Just tied in desktop and able to clear it up in Forms mode or on the Federal review error screen.
Maybe some other issue with the 1099-OID, what values does it have in other boxes?
Maybe try deleting the 1099-OID and input again but without Box 10 from the start.
Don't forget this Box 10 should still be a valid reduction in income but not being reported on the same form as the income if it's similar to the Schwab issue, in which case if it's material you should still adjust for it somewhere either on 1099-OID or 1099-INT.
