The 1099-R should appear on Line 4b of Form 1040. If there was an early withdrawal tax, that would involve Schedule 2, but not Schedule 1.
If there are no amounts on Form 1040 Line 8 or Form 1040 Line 10, then it doesn't look like Schedule 1 contains any taxable information. It sounds like there are some blank fields that may have been carryovers from a prior year, but no additional income from Schedule 1 to report.
It is possible your Oregon kicker could be taxed federally. If you received Form 1099-G for the payment, you would enter that in the Wages & Income > Other Common Income > State and Local Tax Refunds on Form 1099-G section. TurboTax will ask a series of questions to determine if any of the kicker needs to be included in your federal income. The answer is usually not unless you itemized your deductions and deducted your income tax in 2020.
If you are receiving an error, you may want to go back and revisit that section to make sure everything is filled out in its entirety. After entering it, click Done on the State and Local Tax Refund Summary. Then it will take you to Let's See if your 2020 Oregon Refund is Taxable and you can answer the questions from there.
