Income Tax Refund for previous years in current year

Hello Friends,

For past three financial years (2020-21,2021-22, 2022-23) TDS Refund not claimed. Assessee (Individual) not aware of it.

Shall we file belated return by clubbing all previous years TDS in current year Income Tax Return FY 2023 - 24 to get TDS refund?

Income is below the taxable limit for all years.

Thanks in advance.
