How can I find info

the only place would be the IRS - view tax return transcript.

https://www.irs.gov/individuals/transcript-availability 

if that person used a different filing status you won't be able to access it

for more info from Turbotax

note that if someone filed using your SSN, your return will always be rejected if you try e-filing. It will have to be mailed
