From your samsung tab you need to remove your google accounts like gmail and probably also your samsung accounts. By following the procedure bellow you will be able to check the FRP status.
One application at a time in the procedure:
A) Removing your accounts
SETTINGS > Cloud and accounts > Accounts
From there select a google application and click on [REMOVE ACCOUNT]
B) Checking FRP status
Reboot into samsung download mode and in the upper left-hand corner check the FRP Lock status.
If it's ON
then repeat section A) and remove another account.
If it's OFF
you'r ready to install TWRP.
