Hi & welcome! It looks like a Jade plant to me too. It does look like it has been in less than optimal light recently.
The plant database on this site has pics & info about them:
Jade Plant (Crassula ovata)
If you have a spot right by an east or west window, where the sun can shine right on it daily, that would help. At this time of year, a south window is also great, but as angle of the sun gets higher, less light will be shining through a S window with each passing day. It's very difficult for those of us with freezing winters to keep something like a Jade looking like one in a location where it can be outside all year.
If you want to take it outside when the nights are safely above freezing, start slow because plants that have been inside can get sunburned when taken outside. If you start with the first or last hour of sunshine and then ease it toward more sun, a little more each week, you can get it back to looking more perky if the available sunshine through a window isn't enough. There is no requirement to do this, I just wanted to help you avoid sunburn if you did want to take it outside later in the year.
