How to handle a 1099K filed under my SSN for a store I sold?

[Lyss53setl]

I sold my Shopify store in 2021. I got a letter today stating that I owe the IRS $18k because I didn’t notify them of the $44k in SHOPIFY PAYMENTS I made on the boutique in 2022. I did NOT own it then. I called my accountant and they’ve stated the 1099K was filed under my SSN and they’ve asked me to get documentation to submit to the IRS. I have no way to access the store. I cannot get help from anyone at Shopify, I’ve been trying for over 2 hours and can’t even get a chat started.
