Is Turbo Tax on-line safe to use?

For the first time ever, I did my taxes on-line. I was hesitant about giving my personal information to a computer. My wife said, “honey, we have Lifelock, if our identity or money is stolen, we are protected, so give it a shot with Turbo Tax”. This I did. I must admit it was really fast and accepted by the IRS right a way. Question: has anyone had problems with filing your taxes on-line and using Turbo Tax?
