Deductions & credits

I have a credit in my 2020 account , I filed in June 2021 and asked for a refund

while my state refund came federal did not come as of now 

till 2021 Dec it was showing  saying being processed  in where is my refund tool

from jan 2022 it is not showing but giving error

i pulled account and filing transcript and it is showing credit balance for the refund amount

i tried calling them but it goes in automated loop

can i send them the form to check if they sent the refund and possibly lost in transit?

How fast they respond to such mails?

TAS i will try as lost resort if i am eligible to apply
