How do we keep track of the NOLS prior to 2018 vs those 2018 and forward?  And do we get to use up the prior ones that reduce 100% of taxable income first?

I'm sure PS isn't going to be much help in keeping track of this, is it?

I'm really not that well versed in NOL's, barely a handful of my clients have them, so please don't tell me to send them to another preparer that knows what they're doing...I gotta learn sometime!
