Economic Impact Third Payment

Can somebody give me a decent explanation about this whole thing?  My scenario - both the wife and I got letters from the IRS about the "$2100.00" we each received as part of the 3rd EIP.  So, $4200.00 total.  Except we never did.  No paper checks, and I've gone over our bank account several times looking for any electronic deposits.  None.  Nada.  I just did my taxes with TurboTax (late, I know.  I kick myself every year).  Got to the part for EIP.  I wasn't 100% clear on it, even with some research online.  What happens if I tell the IRS I never saw the money?  My guess was they'd assume I was lying, scour my accounts, force me to jump through endless hoops to prove it.  I ended up filling that section out as if we HAD gotten the money (even though we didn't).  Sounds like the EIP was non-taxable, so I'm not being hit for extra income.  Yes, I lose out on $4.2K I could have put to use.  Bummer.  But my biggest goal is to avoid dealing with the IRS and all their BS.   In summary - we never received any EIP money (3rd payment).  IRS thinks we did.  Thinks they sent us $2100.00 each.  I just went along with it.   Said "Yep!  You're right!!  Thanks so much!"  and claimed it as such on the return.  Will that be okay?
