Get your taxes done using TurboTax

So when you say start from scratch you mean I can.not transfer any information from previous tax years unless it is a turbo tax file format? I have several capital losses that need to carry over. There has to be a way. This is ridiculous if not. How is someone supposed to start fresh with no previous tax information? That is important info. The IRS has provided the transcript. How on earth do I enter it?
