You will get a 1099R form from it to enter into your tax return.
You didn't actually pay the tax. You had taxes withheld like from your paycheck. You still have to enter the 1099R and whole gross original amount (before taxes were withheld) with your other income to figure out the total tax (and it may put you into a higher tax bracket) and then the withholding is subtracted from the total tax to figure your refund or tax due. The gross amount shows up,on 1040 line 4a and the taxable amount on 4b. The withholding will show up on 1040 line 16.
