The estimates are optional to pay. They don't get sent to the IRS with your return so they won't be expecting them. If you are receiving a refund or low tax due and Turbo Tax prepared the vouchers then your tax liability was probably reduced by credits. They might have printed out if you got a one time large income this year like if you took a IRA or 401k distribution. You can ignore them if you want. They are just a suggestion.
