Should the AAA balance be $0 in the final return of an S Corp. that was never a C Corp so no E&P to worry about?  Balance sheet is zeroed out at end of 2020.  Distribution of cash and a computer purchased in 2011 that had taken the Sec 179 deduction.  I show a positive AAA balance but should it be $0?  I showed the cash distribution in the AAA but the AAA balance still shows a positive number rather than $0.  Thanks.
