Texas Tax Return: Never Received Refund

I'm hoping someone can help me because I'm getting desperate!

 

I filed my 2021 Tax Return pretty early (February 12). I had to mail my return to Austin, TX as I got married in September 2021 and my husband is British. I normally file electronically / direct deposit through Turbo Tax and have never had any issues. However, because I had to mail my forms out and my husband's ITIN application papers, I am pretty certain my paperwork was lost. 

 

I have tried contacting the IRS and using the 'Where's my Refund' tool which always leads to a wonderful answer of 'No Refund found'. I've tried calling, but no luck as you just speak to a robot who asks the same questions as the survey. I'm really hoping someone can help me - it's so frustrating and I don't understand why we have to mail paperwork in when communication is so much more clear when conducted digitally.
