TTAX 2022 Keogh/SEP/SIMPLE/401K Worksheet--- Which PLAN (box) to use...?

**HAPPY NEW YEAR**

 

I'm a self employed  with an LLC... and a Fidelity Keogh 401K Plan.

 

In going to the above Worksheet and I want to use the max deductible contribution checkbox, NOT clear which PLAN I should enter my data...?

 

Is it the SEP plan line 4d or the Individual 401k Line 6f

 

or another Plan on the worksheet...?

Again, I'm  a self employed  with LC and no employees  and a Fidelity Keogh 401 Plan

 

//thanks in advance\\
