1099 R life insurances

received notification that Life insurance was going to unclaimed funds.  Was able to avoid that receiving the funds.  Life insurance company mailed 1099-R form reporting gross distribution (Box 1) and taxable amount (box 2a) the same amount.  example amount $100,000 would be add to current income  taxable $100,000 + yearly income....

Inquire to taxability of beneficiary of life insurance general answer no taxed,,,,,

From the 1099-R life insurance 100% is taxable.

Is this correct? 

If so tax payment is do when filing Taxes 2024...

Thank you for any advice
