I started my wilkos golden ale kit 18 days ago, today is the first time i have opened up the fv as i now have some videne no rinse

My cameras flash dident work so i have had to edit the photo to make it brighter, but it looks like yeast is still on the top floating with the krausen

I used my sanitised turkey baster to take a sample and the sg is 1012

I am confused with my reading does this mean it is at 1% abv? or do i need to stir / swil the mixture to get the yeast mixed in / wait a few more weeks by doing nothing.
Thanks
