Recertify Income Question - PAYE

I am due to recertify my income by June for the PAYE plan. My servicer is MOHELA. Should I be completing the recertification through studentaid.gov? Also, if I use studentaid.gov, should I be using the certify my income manually option if I don’t want to go the IRS route? I haven’t had to certify in 5+ years so want to make sure I am doing things correctly. Thank you!
