Get your taxes done using TurboTax

I suggest that you list the payments as though they had been filed by the original deadlines (or all in the first quarter) and then attach a statement saying that you actually paid these taxes on the date you did, that you are in an eligible county, and so forth. This will prevent TT from adding the penalty without you having to wait in the hope they will add that variation to the form. The statement will explain why you are doing this if anyone at the IRS reviews it and questions it.
