Gst portal has problems from 2 days. Just do a small experiment. It worked for me just now. Open 3B
1st click proceed to payment, 
2nd click on make payment /post credit to ledger 3rd then click on back button
4th click on reset gtr3B, system will show already resetted. 
5th logout. 
6th login and now check it. Now proceed file will be enabled.

To Raise Token

Browse site : www/gst.gov.in
(do not login)
from menu select Services , } User Services } Select Grievance & Complain

same problem. no luck since morning. Liability ledger shows the debit, credit of amount paid. But File Return not enabled. Afraid to experiment. 

No need to afraid. Just now twice I succeeded to file returns.
