Once you have installed the TurboTax, double click the TurboTax icon on your computer desktop. Once TurboTax has finished updating etc. , it will open and ask for what you want to do. Select start a new return -- it will ask for the 2017 tax file and will find it for you , if it is on your machine.
Thereafter you hit continue and the software will walk you through area by area -- personal info, business income/deduction., personal income, deductions/credits and so on and so forth .
