Traditional IRA distribution before 73

I am 67 and would like to take advantage of the $6000 senior deduction available 2024-2028.

 

My idea is to start withdrawing from my Traditional IRA NOW to maximize this additional deduction over the next 4 years.

 

Knowing I need to use cash to pay the tax on these distributions, HOW DO I FIGURE the tax?  Is there a formula I can use?

 

Or should I just say "screw it" and wait until I'm 73?
