Get your taxes done using TurboTax

so, we have lived together for 3 years(the entirety of my childs life). now she thinks she can claim her as a dependent, even though by law i have the right to do so. so i was subverting her, and started to do my taxes, went to claim her they asked for her social security card info, well now she is refusing to give it to me and has hidden all paper work regarding my daughter. IS THIS LEGAL? In the midst of this pandemic their is no way for me to get the paperwork from the social security office and im not sure which route to take. maybe just not claim her this year and come back next year better prepared?
