Where is my 2022 amended return I mailed in

I mailed around mid December 2023 my 2022 amended tax return.  I just mailed regular mail.  I went to the website to check

There is no information. It has been a month since I mailed it in.  Does this mean it may have got lost?  Should I just print and mail another 1040x amended return?
