RMD Tax

I am 89 and easily confused at the computer. I had meant to keep my tax  form as simple as possible. I blundered into the Turbo Deluxe version when I checked the box "do you want to get as much you are entitled to". 

 

On my filed form did I indicate  a total of $1355.42 tax withheld on my IRA Distribution? With the the $360.59 ,seems like a lot  of tax.
