It seems you're right, they used XXX-XX-last digits of my SSN, the problem is that the digits of my SSN are incorrect in my W2 form, I asked them to update my information but my question will be, can I add the correct last 4 digits of my real SSN in turbo tax app even though that number is not correct in my W2 form? or I need to wait for them to update my info?
