After you file

In Feb 2022, Turbotax stated that you'll soon be able to e-file a 1040-x.  Today, Jan 10, 2023, I completed my 1040x for tax year 2021 but Turbotax won't allow me to e-file this.  The error message states that filing for 2021 closed as of 12/31/2022.   Is Turbotax just a terrible product or am I missing something.   I don't want to print and mail in 33 pages.  The IRS accepts 1040-x electronically for 2021 and any good tax software should work and allow the e-file.  This appears to be a bug in Turbotax as it does not seem to recognize that I'm trying to e-file a 1040x (includes the amended 2021 1040) and that I'm not trying to file a 1040 for 2021 for the first time.   Sadly, not only does this not work but there is no tech support to contact.  Turbotax wants to sell you a product and then just walk away and basically say we got your money so we don't care about you anymore.
