If your husband has already filed a "joint return" (Married Filing Jointly) and omitted your income information, you will have to amend that joint return.
How do I amend my 2019 return?
The program will notify him by email of the status of the return (Filed, Pending, Accepted, Rejected). If it was rejected for some reason, you will have the opportunity to correct it to add your income. If it was accepted, you will have to amend to add your income information.
Follow the program's guided interviews to enter your "income and W-2" information. For example, Form W-2 is entered in the Wages and Salaries interview of Personal Income > Wages and Salaries (W2).
