Help! Wrong fee sent to USCIS!

[Qiuli]

Hi guys!

I need some help/suggestions of what to do after I sent USCIS the wrong fees. So I filed I-751 and supporting documents on 10/29/2020. And I sent $595 + $85 with the documents. Now I know the fee has increased to $760 as on 10/02/2020. So I should send them a check of $760 + $85, correct? Until today 11/13, they haven't sent back my documents and of course, they have not cashed the check. So what should I do now? Should I reprint everything and send them a new check right now? Or should I wait for their response? Please help. Thank you.
