Retirement tax questions

That isn't true.  I withhold tax so I'm not surprised in April.  My box 16 has always been blank or $0.  My box 14 is not, it is the state tax amount I have withheld.  I live in Indiana.  I certainly hope this is resolved.  It wasn't until last year that I had a problem.

 

Can someone remind me what I must have done last year to make this work so I don't fall into the vicious cycle of hitting my head on the wall.  Was it to enter the taxable amount which is what Box 1 and 2A represent for me.? 

 

I haven't started my taxes and I dread this part already.  Ugh!  And I enjoy doing my taxes.
