After you file

I closed a business in 2018 and had a loss and complicated return, so I had my accountant file my 2018 Federal return for me. The return was filed in early February 2019 and I had a small refund check. My 2019 return will be simple (two schedule Cs), no investment gains or losses, nothing else out of the ordinary, and the only thing I am unsure how to handle is how to carry forward the loss. - Prior to 2018, I had always done my own tax return with TurboTax.
