Can we delete a section or delete the enter fields and file again. i am not sure how Retirement Savings Contribution credit is coming. want to delete and fill again.

Is the saver credit so small that you want to get rid of it and stay in the Free Edition instead of having to upgrade?   Go to My Info and say you were a student.  It will disqualify you for the credit and let you stay in Free Edition.

Or—-Use this IRS site for other ways to file for free.  There are 8  free software versions available from the IRS Free File site

You may be able to take the Saver's tax credit for making eligible contributions to your IRA or employer-sponsored retirement plan. Also, you may be eligible for a credit for contributions to your Achieving a Better Life Experience (ABLE) account, if you’re the designated beneficiary.

To remove the credit :

• Login to your account.
• Select Federal from the left menu.
• Go to Deductions and Credits 
• Scroll down to Retirement savings contribution credit in the Retirement and Investments section
• Continue to the screen Retirement savings contribution credit and answer Yes to the question "Were you a full time student during any five month in 2023?"

You won't qualify for the credit if you check that you were a full time student.
