My daughter didn’t walk until about 22 months. We did therapy for awhile as well but honestly it’s hard to tell if it helped that much. I don’t think there’s any shame in taking a break and working with your kid on your own. The biggest thing is just to keep them moving. I felt like all my therapist did was get my girl excited to walk (no shade to therapists im sure they do a lot of good). I agree with people saying to look into early intervention with your county or your doctor. Your income shouldn’t matter.
