R03 Unable to locate.

Ok so I keep getting a R03 - unable to locate account when it comes to billing.

I’ve had this issue before and was resolved. But it’s coming on again. Now I have 2 additional return fees added to my account because of it. Does anyone know how to fix this?

I’ve checked with my Bank (Chase), they said my account is all good. I provided the proof QuickBooks asked as proof for a good standing account. 
 

All my information shows up in my portal- recent transactions from my account, so why does it keep saying my account is not found or unable to locate when they clearly are pulling all the info to show up in my profile/ portal.
