I have a commercial account at a credit union.

Ok, you have a commercial account.

they told me they could no longer accept checks made out to my
business into my personal CU account anymore

But you have a commercial account. Why are you depositing business
checks into your personal account?

and said that it could only be done in a commercial account.

Well, that's ok - isin't it? After all, you do have one. You said you
did.

All they needed was my fictitious name notice

What is a "name notice" ?

to open the commercial account.

But wait - you already have a commercial account. ?!
