OK, thanks. If I understand both kind responses, I should pay 1/4 of the estimated tax liability by the required quarterly deadlines and not all at once in the first quarter. What confused me was the following statement on the turbotax website:
"Should I pay in equal amounts?
Usually, you pay your estimated tax payments in four equal installments. But you might end up with unequal payments in some circumstances:
If you had your previous year's overpayment credited to your current year's estimated tax payments
If you don't figure your estimated payments until after April when the first one is due
If you unexpectedly make a lot of money in one quarter"
I interpreted the last statement as having to pay the entire rollover tax liability in the quarter it was incurred(?)
