clutch not releasing
'Adjusting the clutch as per the manual' I'm guessing means you removed the derby cover AND loosened the cable slack adjuster ALL the way. This would be step one... as I'm sure you are aware.
Then you would've been able to loosen the lock nut on the clutch adjustment screw... which is behind the derby cover.

Then you would've been able to make the clutch adjustment as per the manual.
I like to keep the adjustment screw unchanged while 'un-locking' it. It gives me an indication of how 'worn' the clutch might be when I (lightly) rotate the adjusting screw clock-wise untile it stops. If it's no more than 1/2 a rotation then I surmise the clutch friction plates are still ok.
I then back the screw off between 1/4 and 1/2 a rotation before locking it back up.
I also like keeping the off set boxed in wrench on the allen T handle wrench while making the clutch adjustment check.

These are pics of my friends 07 Street Bob which at the time had 55,000 miles on the stock clutch. When I rotated the adjustment screw clock-wise it turned almost, but not quit 3/4's of one full rotation... yea, some ware... but not much. I backed the screw off just a little more than a 1/4 turn & locked it down.
He now has over 61,000 miles on the clutch with no complants.
Oh, by the way... he's had Amsoil 20w50 in the primary case since day one.
Great explanation and pics.
I would add one thing. Different folks feel the adjustment screw "stop" or meet resistance at different points.
To the OP, there are a few things HD has done right for a long time, the clutch is one of them. Very unlikely it needs anything other than an adjustment.
