I wish I known all the extra tax deductables I could file with my taxes, like child care and health care. I also wish I would have known how cheap it is to go with TurboTax. Going to a other company Cost me hundreds of dollars and TurboTax is so reasonable priced plus you can pay a little extra to get the audit protection. Man oh man do I wish I would have known that the first time i did my taxes.. I use it everytime now..
