K-1

When entering amounts on my 2018 K-1, i entered Business Income as positive when it should have been a negative amount. When I realized this yesterday, i changed it to the correct negative amount and saw it did not change my income or taxes. My question is - do I need to file an amended return for 2018 or can I just enter the corrected amounts in column B in Section A and B of the Passive Activity Adjustment to Income and Loss?
