I've received my W-2 form and submitted it in as of yesterday in the mail I received another another W-2 form and a 1095-b form what do I do

A Form 1095-B is not entered on a tax return.  You will have to amend the 2019 tax return to add the W-2 you received.

An amended tax return, Form 1040X, can only be printed, signed, dated and mailed by you to the IRS, it cannot be e-filed. The IRS will take up to 4 months to process the amended tax return. Wait until you have received the tax refund or the taxes owed have been paid and processed by the IRS before amending the tax return.

On the Tax Home web page when the Form 1040X for amending a 2019 tax return becomes available there will be a link - Amend (change) return
