Did you get a 1099NEC for something? That is self employment income. Did you have a tax due on your return? You must have had some income for it to give you quarterly estimated payments for next year. Those 1040ES are optional to pay. You can throw them away. They don't get sent with your return and the IRS will not be expecting them.
Why is your efile rejecting? A common reason is the AGI. ENTER 0 FOR AGI. The IRS took a long time last year to process 2020 returns so the AGI didn't get entered in time.
When did you file 2020? If it was late in the year or you mailed it, try putting in 0 (zero) for the AGI. And see, https://ttlc.intuit.com/community/rejections/help/what-if-i-entered-the-correct-agi-and-i-m-still-ge...
