After you file

So here is my question, I submitted by return with my bank information , I did not have a turbotax card issued to me. I had the money direct deposited into my bank account. I did have fees taken out of my refund. Does the IRS have my direct deposit information or will I need to update it? I downloaded my return and the routing and account number is my banking information but I have heard that if you had fees taken out that you will either get a check or have to update your direct deposit information with the IRS. So if i have to update my direct deposit information does that mean TurboTax changes my routing and account number to there third party bank so fees can be taken out? I am looking for clarification into this no one seems to know the answer. If I had fees taken out but used my personal banking account for direct deposit do I need to update my information with the IRS?
