Do not bother looking for the word "accepted" on the IRS site. You are past that. The IRS is processing your return. 11 days is within a very normal time frame. Check the status from time to time over the next couple of weeks to see if you get approved.
When you are entering income on a joint return, every income entry screen will either have a spot with both spouse’s names there, or when you click to enter a W-2, 1099R, etc. it will ask you by name which spouse it is for. You do not have to wait for the software to “ask” you for your spouse’s income.
