if you receive an incorrect 1099, reach out to your client and try to correct it. If this doesn’t work, contact the IRS at (800) 829-1040 for instructions. You may have to include a letter with your tax return stating why there is a discrepancy.

In some cases, the 1099 sender may not be willing to work with you or be difficult to reach. In this scenario, there is no quick resolution. You’ll address the discrepancy on your tax return on
a) schedule 1 report income with a complete description it's erroneous on line 8z and subtract the amount on the same line
or
b) create a schedule C showing the amount as income
in deductions on schedule C list as error in reporting the same amount
You will need to show the client reported an erroneous amount on your 1099 and attach a statement to explain the difference. In your statement, include the amount reported, the difference, and the correct amount. Unfortunately, a 1099 discrepancy puts you at higher risk of being audited, but your explanation may serve to reduce your audit risk.
in the future always use the S-Corp EIN on the W-9 part I leave the SSN line blank.
