I know now that I should have waited, but this was my first ever amended return. When the amended return was filed using TurboTax, the $1,800 was the total tax owed. I thought it would supersede the previous return, but both the original amount owed and then the new, larger amount owed were both withdrawn in two separate transactions. Thus, the IRS has $1,200 of additional payment. I am concerned that the $1,200 is labeled as Balance Payment rather than Estimated Tax Payment on the IRS site.
Audit Defense won't get involved unless I'm audited.
