@lotoftaxes123 I used Option A. If you divide the amounts on each W2 by itself, it would come out to the same result as Option B but its less confusing and at least you can more easily understand how you got to the final numbers. It would also be easier for the IRS to figure out what you did with Option A. I don't like lumping numbers together like Option B only to try to reverse engineer what I did if I ever needed to explain it later.
For things like stock sales, dividend, interest, it's the same thing; divide the income between spouses on the 1099 just as you did with the W2. In the Community Property Section on Turbotax, there are also sections for Interest and another for Dividends to confirm the allocations to complete the 8958.
On "Question 2", ALL W2s from all employers from you and your spouse should be listed here if you entered the W2s correctly. There are 3 columns in the Wages section in the Community Property Section; one for you, spouse, and Total. You have to enter the spouse portion manually in the Spouse column and then make sure the Total equals the amount on the unaltered W2, as well as confirming that the total also equals the sum of the columns for you and spouse.
Hope this answers your questions.
