Instant Cash ISA/ Transfer/ New Cash ISA

Hello HMRC Admin, I have the following ISA accounts and please help to clarify. 1) Instant cash ISA at bank A opened in Jan 2024 – 1 year fixed rate cash ISA opened in Jan 2023 (Tax year 2022-2023) 2) Instant cash ISA at bank B opened in Jun 2024 – 1 year fixed rate cash ISA opened in Jun 2023 (Tax year 2023-2024) Not sure if this is acceptable that I have 2 instant cash ISA account currently? Meanwhile, if I transfer 1) instant cash ISA £20,000 to a new cash ISA account this month (July 2024, tax year 2024-2025), is this means I have already used the entitlement of £20,000 tax year 2024-2025 and I cannot open another cash ISA and pay new £20,000 into it? Please kindly advise. Thanks.
