Do I need to include any page which lists all the documents being included (W2) along with the 1040?
My best understand so far is that I can just print the 1040 from the IRS website (it's okay to print in black n white) and then include a Copy B of the W2 (or the entire W2 with all copies on it, the 1040 instructions note that papers should not be cut).
Assemble any schedules and forms behind Form 1040 or 1040-SR in order of the “Attachment Sequence No.” shown in the upper-right corner of the schedule or form. If you have supporting statements, arrange them in the same order as the schedules or forms they support and attach them last. File your return, schedules, and other attachments on standard size paper. Cutting the paper may cause problems in processing your return.
Don’t attach correspondence or other items unless required to do so. Attach Forms W-2 and 2439 to Form 1040 or 1040-SR. If you received a Form W-2c (a corrected Form W-2), attach your original Forms W-2 and any Forms W-2c. Attach Forms W-2G and 1099-R to Form 1040 or 1040-SR if tax was withheld.
