I was wrongfully claimed as a dependent and I made more than $3,000 last year.

Since he claimed you as a dependent on his tax return you need to indicate on your tax return that you can be claimed as a dependent so you can e-file your tax return.  Your dependency is entered in the My Info section when you edit your name.

If he provided over one-half of your support and your gross income was less than $4,200 then he could claim you as a dependent on his tax return under the Qualifying Relative rules if you met the other requirements under the rules.

To be a Qualifying Relative -

1. The person cannot be your qualifying child or the qualifying child of any other taxpayer. A child is not the qualifying child of any other taxpayer if the child's parent (or any other person for whom the child is defined as a qualifying child) is not required to file an income tax return or files an income tax return only to get a refund on income tax withheld.
2. The person either (a) must be related to you or (b) must live with you all year as a member of your household.
3. The person's gross income for the year must be less than $4,200 (social security does not count) in 2019
4. You must provide more than half of the person's total support for the year.
5. The person must be a U.S. citizen or a U.S., Canada, or Mexico resident for some part of the year.
6. The person must not file a joint return with their spouse.
