the federal deadline for 2020 returns is 5/17/2021. however, rather than filing you can get an extension that will give you until 10/15/2021 to file.  if you owe taxes they have to be paid by 5/17.  it's totally up to you as to which option to choose: file now and amend later, wait to see if you get it in time to timely file by 5/17, or extend. 

Yes, according to this IRS link, "if you file your return claiming your daughter as a dependent and don't provide her social security number (SSN) on your return, the IRS will not allow you to claim her as a dependent."
