Retirement tax questions

Thank you. If I understood it right -

It means that in the Line item 'Any contributions you personally made (not through your employer)' 

I should enter the sum/$ amount of contributions made outside of my payroll (e.g., via direct deposit to HSA) and elected to be counted towards 2024 by the current date?

Before filing/submitting a Tax Return for 2024, I guess it is better to contribute as much as I can/want [within the required limit for 2024 - $4150], so the contributed amount towards 2024 is valid on the Tax Form.
