Administrative Forbearance

I am currently in an administrative forbearance (Not the COVID one). I called Nelnet to cancel it so I can start making payments again. That was a little over a month ago. My interest is starting to accumulate again. Does anyone know how long it takes to get out of forbearance? Like weeks or months??

(I consolidated in the new SAVE plan and I'm still making my monthly payments, but the forbearance causes the interest to accumulate)
