NO. You cannot use a 2023 W-2 on a 2024 tax return. You made a mistake last year and did not include all of your income on your 2023 tax return. You need to amend your 2023 return to put in that W-2--- or someday you will get a letter from the IRS.
See this TurboTax support FAQ for amending a tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-change-correct-return-a...
Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.

The current online program is only for 2024 income. If you have more than one W-2 for tax year 2024, wait until you have ALL of them and include all of them on the same tax return. You cannot put income from any other year on a 2024 return.
