After reviewing and submitting my returns, I realized I entered in the amount of both jobs into the 1st job, then the correct amount for the 2nd job. Can I correct it?

If your e-filed tax return is rejected by the IRS then you can make your corrections and re-file.  If the tax return is Accepted by the IRS, then you need to wait for the tax refund to be received or the taxes owed and paid to be processed before attempting to amend the filed tax return.

Use this TurboTax website to check the status of an e-filed return and if it was either accepted or rejected - https://turbotax.intuit.com/tax-tools/efile-status-lookup/

See this TurboTax support FAQ for amending a 2018 tax return originally completed and filed using the online editions - https://ttlc.intuit.com/community/amending/help/how-do-i-amend-my-turbotax-online-return/00/27577

For W2 or 1099Misc income?   If you efiled and it is accepted you will need to mail in an amended return.  So hope that it rejects.   Check your efile status here

If the IRS accepts your return, then you have to wait until it has been fully processed and you have received your refund. THEN you can prepare an amended tax return 1040X and mail it in. You cannot e-file an amended return. Meanwhile, DO NOT change anything on your return until you start the amended return.
