I only got one of my W2’s back from one of my jobs and didn’t get one for my other job can I still file the one that I got without filling the other one?

ALL of your 2019 W-2's are supposed to be on the same tax return.  Make every possible effort to get the other one.

Every 2019 W-2 that you received must be reported on your 2019 tax return, even if they are for small amounts.  Remember that each one of those W-2’s has your Social Security number on it, and that income was reported to the IRS by the employer.  You do not want to get in trouble with the IRS for under-reporting your income.

ALL of your W-2’s must be entered on the SAME tax return.  After you enter the first one, you click Add Another W-2.

W-2's come from your employer, and they have until Jan. 31 to issue it.  Some employers allow you to import the W-2 through the software, but for security reasons you still need information from the actual W-2 to import it.   You might need to phone, email and/or snail mail an old employer to make sure they know where to send your W-2.

 No.. You need all of you income to file... Your employer was required by law to get the W-2 to you by Jan 31.   Contact the employer for a copy.

[Paraphrased from IRS rules]
Can you file without having received your W-2? Yes, but only if you have not received it by the end of February, and you have contacted your employer and attempted to obtain it, and you still have not received it then you contact the IRS (see the link below), then if the IRS is not successful in getting your W-2, you can use form 4852 in place of your W-2. But you MUST speak to the IRS before doing so. Otherwise, you cannot file before you receive your W-2.
