Hello, on my tax return I indicated that someone else would be claiming me, but when my mother (who also used turbotax) tried to claim me, it said she couldn't.

Because they said my social had already filed, but I indicated I will be claimed by someone else.

To prevent fraudulent returns, the IRS will only accept each dependent's SSN once in their e-file system.  Because you filed first and used your SSN, no further e-files using that SSN will be accepted.  Your Mother will need to print, sign, and mail in her tax return to the IRS.  Her return will be accepted if she paper files.
