Yes amend to a joint return. If someone told you to file separately because your spouse had no income that was poor advice. You can file a joint return even if one spouse had no income. When you amend your return make sure you complete the Federal Review section to get the stimulus checks----use the recovery rebate credit to get the 1st and/or 2nd stimulus checks if you did not receive them.

The stimulus check is an advance on a credit you can receive on your 2020 tax return. If something went wrong or you did not get the stimulus check in 2020, you can get it when you file your 2020 return in early 2021
The Recovery Rebate Credit will be found in the FEDERAL REVIEW section. ( you should see "Let's make sure you got the right stimulus amount”) If you are eligible it will end up on line 30 of your 2020 Form 1040.
Make sure that you enter ALL of the stimulus money received for the 1st and 2nd stimulus for yourself, your spouse and your children.
