I was just finishing a corp return, using 2022; corporation fiscal years ends late in the calendar year.  I went to look at the tax history to do a little comparison, and the tax history shows that there was zero tax due in the prior year.  I know that isn't the case.  I opened 2021, and it shows the tax due.  However, it doesn't pull up many years on the tax history tab either.  The NOL worksheet has different numbers between the two years; it is as if it didn't get adjusted correctly when it transferred. Is this a known problem?  How do I fix the NOL to be accurate?
