Retirement tax questions

Sorry to jump in, but I had an RMD on a small account and the distribution was $115.67.  I asked Vanguard to withhold the entire amount as a NY State tax deduction.  

 

Now I can not E-File because box 14 (State Tax withheld) EQUALS box 16 (State distribution).  I did not have to withhold the entire amount; I could have done this any other way.  Why (rhetorically) is this a problem???

 

Anyway, I am guessing (because I am getting refunds) that maybe I will have to ask for an extension and sort this out tomorrow.  Woof.

 

Any suggestions.  Thanks in advance
