What to do now!!

[the red devil]

Made a TT Landlord clone 8 days ago. After 2 days the head was gone thought something might be up but carried on. The starting OG was a little high at 1054 (must have got some good grains). Checked today and the SG is 1020 Should have been down to around 1015 by now. Not sure whether its going to get any lower, even if I leave it a couple more days.
What to do? Do I keg it anyway, and put up with the sweetness. Do I give it a bit of a stir and hope the yeast starts again. Should I add a little more S-04.
Please help

Is this the 1st hydrometer reading you have took at 1020? If so, give your brew another 24-48 hours & take another reading. I would not stir it yet, you may areate it if you do, not a wise move at this stage of the fermentation.

First reading, yes! I'll give it another check later tomorrow. Cheers
