Hi @Maegan Coolbaugh. Sorry for the delay. I've generated a 3D build of your room. Placed your tv on the opposite wall with a panel behind it. A couch facing the tv and another one next to it forming an L shape.Two swivel chairs that can easily be rotated in any direction or moved away when not in use. Completed the seating arrangement by adding a rug. It is important to pull up the area together which can be aesthetically achieved by adding a rug that goes well with the items placed on it.
If you are planning to take down the short wall near the stairs, great! Else you can simply place a see through bookshelf which can act as a partition to diving a small space dedicated to reading/work or serve as a private conversation spot.
Placed dining near the window. It could also float a little more towards the kitchen. I placed a crockery unit to provide for some storage. You can add more storage based on your requirements.
Let me know if this was useful or if you would want me to work on more layout for you.
