I don't believe this is a question that Turbotax Support will address.
You have until April 15, 2023 to amend a 2019 tax return assuming the original return was filed on time. Unfortunately, the only thing you can do is wait. The IRS was never good about taking phone calls and they're worse than ever now. I think it took 11 months for me to get paid the last time I filed an amended return.
In March, 2023, you can think about mailing a second copy. It's a bit dangerous to send more than one return for the same year since the IRS can get confused, and it might still be in a pile waiting to be opened. I wouldn't mail a a new copy until the last minute. The current version of form 1040-x is revised to be universal and not specific to any one year, so mail the return to the address indicated in the current instruction rather than in the 2019 instructions.
If you have an urgent situation that needs correcting and you are worried about penalties, you may want to speak to a professional.
