I filled my taxes and put to mail because I did not have info prom last years income. I now have the info and would like to do it online, but how?

As long as you haven't already mailed your 2018 paper return, you can switch to the e-filing method (through October 15, 2019). Please see this TurboTax FAQ, How do I change from mail to e-file in TurboTax Online?https://ttlc.intuit.com/replies/5561257
