H4 EAD to H1B lottery selection

I got H4 EAD Last year and started working for Employer A. In the same month I got another job offer and started working for employer B as well. I have W2’s from both the employers now.

I have applied for H1B from both the employers and Employer B H1b is picked in the lottery.
Now planning to quit employer A after the H1B approval.

Question is, H1B documentation for Employer B, do we need to provide both the W2’s and 3 months recent pay stubs (both meaning employer A’s W2 and pay slips and Employer B W2’s and pay slips) ?

any help is appreciated

Your question is not clear. Why would you need payslips if you are filing H4 to H1B COS?
