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?

The IRS may adjust your federal tax return and remove the credit.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

The IRS Form 1040-X for amending a 2020 tax return is scheduled to be available on 03/18/2021 (subject to change)

If you made a mistake in reporting the amount of stimulus received, the IRS will most likely identify the error and adjust your refund.
