Excess Contribution to Roth IRA

I know this topic has been covered but I need some clarification.   I made an excess contribution to my Roth IRA in December of 2018.   In March of 2019, I removed the excess and applied it to my 2019 contributions.    I have received a 1099-R stating that I had $45.66 of taxable income earnings from this excess contribution, and Turbo Tax is telling me I need to amend my 2018 tax return, even though this was earned in 2019.    Do I claim this 1099-R on my 2019 taxes, or do I amend my 2018 taxes?   If so, do I only have to amend my gross income, and not change anything on the excess contribution?

Thanks for any clarification
