Roth IRa cashed out code T shows no taxable amount

Initial start up was 6.5k. Cashed out with +10k after 7 years. The 1099-R form shows no taxable amount and the 2b check box checked for 'Taxable Amount Not Determined'.

In fact the rest of the amounts are $0.00.

Distribution code T. Held Roth for 5 years now age 67.

 

Is this truly tax free? I have to get affirmation because nothing is tax free.
