Thank you for contacting us, darkred1,

You'll want to enter 01/04/2020 as the effective date on the VAT settings to pull up the return. Doing so will help you record a historical payment. 

Let me show you how:

1. Go to the Taxes menu and click VAT. 
2. At the upper-right, click Edit VAT and then Edit settings. 
3. Change the Effective date for new scheme to the date you filed the return. 
4. Click Save. 
5. Under the Filed returns section, the reports will then show up.
6. Click Record payment. 
7. Once done, click Save. 

The VAT exceptions and reports page will tell you more about this and what to do if you need to change the amount.

Stay in touch if there's anything else you need. I'm always right here to help.

Thank you and stay safe!
