I have an insurance mature in January 2023 but I only have the cheque deposited in the bank in late April 2023. Should I recorded any gain in year 2022-2023 or 2023-2024?

Dear Sir, I will fill in the Self Assessment for 2023-2024 with a deadline by the end of October. However, the management company then sent a letter informing me that additional cost was incurred for the year ending 31 December 2023. I have not yet received the invoice and if it comes later than the deadline for self-assessment, how can I report the loss? Since the earnings from the rental are little, I would lose the money from paying more tax than I should. ( Next year, there will be high service charge demand for cladding remediation as well and surely the rental income would become negative then)

I try to use online self assessment form to report disposal of shares but it only allow input of around 20 disposals.
Can I attach an excel sheet to report the disposal or must I purchase a computer program to do so?
