Turbo Tax can't find my refund, IRS gives mixed information

My 2020 1040 was filed ~2/9/21 on Turbo Tax and accepted by the IRS on 2/12/21, with a refund due me by the IRS. In late April, I received a notice that suggested I needed to file an amended return due to changes in a law that would increase my refund. With help from a TT specialist, I did so, and the amended return was accepted by the IRS on 4/29/21.  In trying to figure out when I will receive my refund, I used the IRS online tool and it told me this:

We cannot provide any information about your refund. Be sure to:

  • verify your filing date;
  • check with your tax preparer or tax software provider; or
  • verify you received your electronically filed acknowledgement e-mail.

If you filed a complete and accurate tax return, your refund should be issued within 21 days of the received date. However, processing may take longer under certain circumstances.

I then tried to contact TT but could not get past the bot to talk to a live person. The bot only said it couldn't find my refund(!) based on my social security number and zip code.

I have my confirmation emails saying my returns were accepted, but have no idea when I will receive these much needed funds. Can anyone help add clarity to this concerning situation?
