Troubleshooting

If I am to understand correctly, one does not need to make any changes manually to the T691 if they entered their data in the T-SLIP panel. For example, if one entered in the receipts->paid to earn inv. income (interest expense) and it seems to not flow through to the T691 as it is fully deductible against AMT? Prior to the March 18 or so update, am I to understand that it was incorrectly considered 50% deductible against AMT but now that it is netfiled certified we see that money borrowed to earn investment income is not 50% deductible for AMT purposes?
