Is it correct that I would probably use the $49.99 Turbo Tax service since in addition to wages paid to me in 2018 I received a final wages payout and also a small amount from my pension.
It will be similar with all other things remaining the same. You will lose your exemptions and your property taxes will be capped at $10K. Your reporting will be different in that you will list your final wages via your W2 but will list your pension earnings (and Social Security) on a different line. The BIG change will be in the tax rates due to the changes in the tax laws. Make sure you withhold enough for next year since your employer will no longer be doing that.
