Is this ISA allowance calculation correct?

Hi all I would appreciate much for the community's input if my understanding of ISA allowance is correct. A hypothetical scenario:

Tax year 2025/2026: Has £20k in cash ISA with provider 1

Tax year 2026/2027: Contributed £10k fresh funds in cash ISA with provider 2 with higher interest rate, so also withdrew £10k from provider 1 and put it in provider 2

I did not ''transfer'' my £10k between two accounts, but instead withdrew from provider 1 and then deposit into provider 2.

Am I right to say that I could still deposit £20k more for the current tax year (£10k from this tax year's allowance + £10k of ''replaceable'' fund that I withdrew from provider 1)?

Many thanks
