VAT submission not showing up

Hi I input the VAT return just after midnight on the 1st and HMRC reckon they've got it but its not showing anyway like it does normally and when try and resubmit via the software says duplicate return?? the agents don't seem to know what to suggest other than wait

What do you mean when you say you "input the VAT return just after midnight"....you cannot file VAT return manually by inputting numbers onto a VAT return, they can only be filed via accounting software. Two exceptions to that, you have special approval to file VAT returns manually (inputting values by keying them into the VAT return boxes) or if this is your final VAT return just before deregistration. That the software is stating a duplicate return would suggest the return has been submitted, it can take 24hours for HMRC systems to update, but that updating takes place overnight, so if you file after midnight, may not show up until the following day.
