the AICPA has nothing to do with those Stimulus payments. you are not doing financial statements. the stimulus payments, the $1200 and $500. received are non-taxable income. even if you received too much it will not have to be repaid. I certainly would not be making a bookkeeping entry for these.
For any PPP loans even if the AICPA issues guidelines for accounting for them, how they say to record them for book purposes can be completely different from how they are treated for tax purposes.
