Roth IRA partial distribution

I took a distribution from my Roth. I entered the 1099-R with a 7 code. I noticed that the gross distribution and the taxable amount are the same. I had the federal and state income taxes taken out of the distribution as I was 63 and working at the time. Since this is with the other 1099-Rs, does that mean that it will be taxed again? The more I try to look into the topic, the more confused I get. 

I hope someone can decipher my confusion. Thanks in advance
