Calming my dog down

My partner and I adopted a small mix breed (we think she is daschund mix?) dog on Christmas Eve who seems to be having issues settling down. We think she is about 1 year old, so still sort of a puppy. She is a very energetic, very smart dog who can just about get into anything. So far she is doing pretty well, but the only issue is that she seems aroused all the time. Occassionally after a long walk in the morning she’ll lay down in my lap and sleep for hours at a time, but most of the time she is pacing around the house constantly and trying to jump on tables or look for food. I know dogs can be overtired like babies so usually I try to give her a chance to settle down, maybe 45 minutes, and if she can’t I put her in her crate. I guess I am looking for hope that we are doing the right thing. She is usually pretty content in her crate. She will occasionally bark or cry for a few minutes, but settles down and goes to sleep. The second I let her out though, usually 30 minutes to an hour later she is back to pacing and jumping on furniture. I guess I am looking for hope that she will learn how to chill out. Occasionally she chooses rest on her own or chews on her nylabone (which I’m a bit paranoid because she’s a bit of a power chewer). I walk her about 45 minutes a day, we make her work for all of her food through training or puzzles. I’m a little lost as to what to do other than crate her when I can’t be supervising her. She never seems anxious, just aroused and obsessive.
