If you used online TurboTax you should not try to mess around with it to create different scenarios or you will destroy the tax return that you e-filed. You can use the "what -if" feature of desktop download software or create multiple returns and try out various scenarios if you have the desktop software, but do not try that with online. You can create a "dummy" online account if you want to play around, but do not --- do not-- mess with your already filed tax return.
