Rectification under section 154 of Income Tax Act

I have submitted rectification request for Reprocessing my ITR as there was tax credit mismatch. CPC received on 6th April 2021, rectification submitted on 9th April 2021.
Kindly advise how much time it will take for my ITR rectification to get processed, I received the rectification submission acknowledgment but not getting the rectification completion timeline from anywhere.
Because of this my Homeloan got stuck with loan appraiser and he wants the rectification to be completed.
Please help.
Thank You
