Is there specific advice you need? Are you asking for ideas for moving your furniture from its current location?

Yes. The couches can all come apart and resectioned if need be. I'd also like to update the fireplace somehow and style the room better. Any suggestions are helpful

Think about mounting that TV somewhere else in the room, maybe cornered on an articulating mount. That's the biggest thing influencing and limiting your options.

can we see on the other wall?

Perhaps this is not the correct room for the TV. What is the room beyond this room? Appears to be a den.

The room beyond is the formal living room. This room pictured is the family room open to the kitchen

Does anyone know how to use the houzz app to take pictures of furniture at online stores and place them in a room?

At first glance, the room looks quite dull and cluttered. Two things obstruct the design flow; the furniture blocking the path through doors and the second ottoman (the grey one) appears to block the movement.

First, you can rework the sectional into a straight sofa, as katin paradise mentioned. This will let you have more space while clearing the doorways. Besides, I would recommend adding some colors for a lively feel. You can opt for some modern art, use some drawers/stands to place/store things. Also, replacing one ottoman with a sofa table could add a more functional area to the room.
