Are you using the DirecTV remote to control the TV?
On the DirecTV remote there is a switch at the top on some of them, if you moved that to TV or something else it will might stop controlling the DirecTV which is what you need to get out of that screen. See a pic here, the switch is all the way on the top and needs to be set to the left: https://seniortv.com/directv-remote/
