Consent for student gov to access IRS?

Hi,
I just reapplied for IDR through student gov. My renewal was last month but my service provider never sent me any correspondence until it was a bill. Anyway, I gave consent for the app to access my IRS records. Was that a bad idea? Do you all recommend self-reporting instead? I know there’s a way to withdraw consent but I don’t know if that would significantly slow things down more than it already is.
Loan is from 2014 so I believe it’s still eligible for the old SAVE plan until 2027. Student gov let me apply but there is also conflicting information about it going away.
