Is there a special form for stimulus refund?

Yes, there is typically a special form for claiming a stimulus refund, which is often included in the federal tax return forms. For example, the IRS used Form 1040 and 1040-SR for the Economic Impact Payments (stimulus checks) issued during the COVID-19 pandemic. Taxpayers could also use Form 1040-X to amend a prior return if they did not receive the full amount. It's important to check the latest IRS guidelines for specific requirements and any updates for new stimulus payments.
