Don’t understand tax refund for savings income

Can anyone help me understand this tax refund?

I’m currently on maternity leave. I’m a low earner (under the taxable threshold). But currently saving for a mottgage with partner so have a Lifetime ISA. 

But the savings income doesn’t correlate with any savings amount we have and I wasn’t aware I paid any tax?!? 

what am I not understanding??

Is it tax deducted from interest paid alongside a PPI refund?

Nope, I haven’t claimed any PPI refund

Does your personal tax account give any details of the source of the savings income?
