When CARES Act is selected the Federal return no longer calculates Form 461, and the adjustment for ELA is not reported on Schedule 1, line 8. However, New York continues to show this adjustment.
According to New York N-20-7:
"...any amendments made to the IRC after March 1, 2020, will not apply to New York State or New York City personal income tax. Therefore, any retroactive changes made to the IRC after March 1, 2020, should not be taken into account when filing your 2019 New York State personal income tax return."
When the CARES Act checkbox in Input Return ⮕ Miscellaneous Info is checked, the Federal return will not complete Form 461 and the adjustment does not flow to Schedule 1. However, because it still applies to New York, this adjustment will show on line 16.
When the CARES Act checkbox in Input Return ⮕ Miscellaneous Info is not checked, the Federal return will complete Form 461 and the adjustment does flow to Schedule 1. Because New York reports Federal amounts, and then applies adjustments, no adjustments are necessary. This is why the adjustment does not show on line 16, it has already been included.
