You don’t get the tax back until you file the next year and you won’t be able roll the tax back in.
If available roll it to an Ira which doesn’t have the 20% mandatory tax and you can do the 60 day rollover there, otherwise it’s just better to do the loan and repay it like you would a 60 day anyways.
Also remember if you do a 60 day rollover you can only take advantage of that once every rolling 12 months
