I have a simple situation...well sort of....

I have to file the 2020 tax return for my elderly parents who wouldn't otherwise have to file a tax return except that the IRS made a mistake and didn't issue the second rebate check to just one of my parents for $600.  However, I cannot use the free IRS Tax submission program because it doesn't allow for entering in a large NOL non operating loss carryforward. So, which is the least expensive version of TurboTax that I can use in order to file a tax return that will allow me to enter a NOL, or should i do a free version, print it out and add a schedule? help
