Employer SIPS - vested matching question

[Gigamoons]

I'm in an employer SIPS scheme.
For the last tax year I have approx £1,500 "Vested Matching" paid in two little lumps.

I've done the calcs on the relevant pay slips and the company have included these amounts within "taxable pay".

When doing my tax return, is this £1,500 claimable within my Dividend allowance? (6 April 2022 to 5 April 2023 £2,000)
