UK - How to adjust Statutory Maternity Pay and other family leave types

Summary:

Overpayments across year end require balance adjustments to SMP and SMP recovery. What is the best way to do that?

Content (please ensure you mask any confidential information):

When someone on maternity or any of the (many) UK family leave types is overpaid in March and this is recovered in April, this creates a need to enter balance adjustments against the total SMP paid and SMP recovery in the previous tax year, so that an adjusted FPS and EPS can be sent to HMRC.

The seeded elements have "Allow User Entry" unticked on the inputs that you would need to enter a balance adjustment against them, so as standard they can't be used for balance adjustments.
