Thank you so much. I will check to see if there were other refunds (or, I will check with the state office). It looks as though I will be paying a federal tax on that refund (I had an itemized federal return). Moreover, it appears that if I had taken the standard deduction for 2018 instead of itemizing, I probably would have avoided paying that refund tax (even though itemizing lowered my taxable income by $113, it turns out I will be paying more than that with the tax on the refund).
