1099-R having state distribution

I am from Texas and I have my traditional IRA account from TD Ameritrade which is in Omaha as per the TIN information provided in my 1099-R form. I did a traditional IRA to Roth conversion (converted my non taxed money which I had in traditional IRA to Roth IRA), in 1099-R form Box #16 State Distribution has amount against it. 

 

Question: Having amount in box 16 for state distribution is correct? I am from Texas, want to make sure I am not paying extra taxes

 

P.S. I did a backdoor roth conversion it doesn't have box 16 with any value.
