What do you mean synced? When you use the Desktop program your info and returns are only kept on your computer and not saved or stored online. Desktop and Online are 2 separate products and do not have the same features. You can transfer the previous year form either version into either one. I don't think they can ever be "synced".
For the Desktop program you have to check the filing status inside the program. Open your return and go up to menu item File > Electronic Filing > Check Electronic Filing Status
