Short-term transactions are sales or exchanges of cryptocurrency that you bought and sold in a year or less. Noncovered means your crypto exchange did not report your cost (basis) to the IRS.

Your may have to add your cost. Noncovered transactions may have a blank cost because it is not reported to the IRS. If you get those errors, check your records or brokerage statement to find a cost basis.
