This problem happens when you don't include Form 1095-A, Health Insurance Marketplace Statement. It also happens when the information on the form doesn't match what the IRS has in their database. If you don't have your 1095-A form, you can get it at HealthCare.gov or your state's Marketplace.
Once you get the information you can enter it on the return:
- Go to the Do you have Form 1095-A info ready? screen
- Answer the questions and enter the details from your Form 1095-A
- When you’re done, select File from the left menu and continue through to re-file your return
