At the time of filing we had not received our second stimulus check and stated so. I went out of town and my wife received and cashed the check. What do I do, amend?

I claimed on my tax return that we didn't receive the second stimulus.  Then we received it and my wife cashed it.  The IRS hasn't provided a status or why they haven't issued the refund and they are impossible to get a hold of.  I'm assuming we have to amend the tax return?

If that is the case - Turbo Tax doesn't even have a 1040X yet until March 25th.  I can find it on IRS.GOV directly - why does TurboTax take so long?
