Someone claimed my dependent

My daughter,  who lived in California for the past 3+ yrs, claimed my granddaughter.  I've been the guardian of my granddaughter during this time. I tried to e-file my 2020 tax returns but was denied due to her claiming her. Followed the instructions and mailed a paper return. It's been since April and I haven't heard from the irs. I got my refund but now what? Never received any stimulus for her either. She's 5 if it makes a difference.
