After you file

Still not really clear, I'm not sure where

 

...yes...look at your actual form 1040

 

Based on what you've said...perhaps.

...was your calculated Federal tax actually $2168  ??  (line 24)

...you prepaid $1981, thru withholding

....leaving with you owing $187 more.

(edited) Line 24 of your Form 24 1040 is you tax assessment before applying withholding (plus other possible credits down to line 33).
