Thank you, SusanY1, for looking into my file.
I adjusted the cost basis for the loss transaction to zero cost in 1099-B and updated 1099-K loss amount accordingly. Then, Smart Error Check no longer gives an error.
How do I adjust the cost basis after that? If I change the cost basis back to the correct onse in 1099-B and 1099-K, I get the same error. Should I leave the 1099-K loss amount as zero assuming the 1099-K information doesn't get sent to IRS?
Best regards,
Shig
