Ouch! I'd urge you to rethink the use of the SharkBite in that application...
The excess solder on the pipe, the green corrosion on the pipe, and the bending of the pipe, will all make a strong possibility that the pipe is not round enough or, smooth enough to get a good fit and seal in the SharkBite.
With this lack of a good seal there is a strong probability that you will have a leaking connection either immediately or, at some undetermined time in the future. I use SharkBites myself at times but this is not one where I would do so.
The thing to remember here is that it is the main shut off valve to your home and is the only means that you have of shutting off the incoming water to your home. If you were to have a leaking connection blow out not only would you face disastrous damage to your home before you see the leak but if the leak is on the wrong side of the valve you would be sitting there helplessly waiting for the city worker to respond to your call to have the water shut off at the curb.
I highly recommend replacing the valve with a full port 1/4 turn ball valve that is sweated on in place. The steel pipe is another concern in itself and if you are not up to the tasks involved I would recommend hiring a plumber.
