USED IRS IP PIN tool to get IP PIN after filing taxes (taxes were accepted and I've already got a refund)

Hello,

 

So I e-filed my taxes earlier this year and they were accepted and I got a refund. I've recently had some identity theft issues (at the state level) and thought getting an IP PIN would be a nice safeguard for next tax season. I went through all of the hoops and got the pin only to find out the pin is for this years taxes. I would have waited if I had known that.

 

With that do I need to do anything about my taxes that have already been filed, accepted, and processed through the IRS? I'm assuming not unless I hear from the IRS as I got this pin after the fact do to me wanting to protect myself.

 

Thanks for the help.
