Why do I have an entry on line 6 of the Social Security Benefits Worksheet when I have no adjustments to income from Schedule 1?

I have this same question, and a possible answer, but I'm not at all sure. I have nothing on Schedule 1, but I do have an entry on  line 6, as do you. The amount is the exact same as a cash contribution I made to charity. (See 1040 line 10b)

Could that be it? Do you have an entry on 1040 line 10b, and if so, is that what is on line 6 of the worksheet?

Apparently, if you take standard deduction (no schedule A) but gave cash to charity, you get a deduction on the 1040.

It doesn't make sense that nothing shows on Schedule 1, though... but this is the only link I can see.

You are correct.  The 1040 Line 10B charitable donation adjustment to income is being added to the amount from Sch 1 to equal your Line 6 adjustments on the Social Security worksheet.  This is a new adjustment to income in 2020 for non-itemizers.  For 2021, that amount will jump to $600 if married filing jointly.

I do have the exact same situation as you described.  I also guessed the $300 is the allowable ceiling on the charitable contribution, which is an adjustment to income.  So, I filed as it stood.

Yes,  $300 is the allowable ceiling on the charitable contribution, which is an adjustment to income for 2020.
