Shots Up forms spring AAU teams but not for every age group, depends on turn out and availability of coaches. It is hard yto know of upcoming tryouts unless you follow a team on Instagram or via word of mouth.
If I were you, I'd attend local tournaments with Girl teams in your daughter's age range, study the level of play in comparison to your daughter's skill level, then when you find a match (skill level and practice location), go speak to the coach to express interest.
In the mean time, sign her up for summer camps. My son always improved over the summer by attending lots of camps.
