Confused First-Time Filer: What Does Cycle Code 20250602 Mean on My $9,502 Tax Refund Transcript?

I keep seeing everyone talking about cycles and cycle codes but I have no idea what that means. Just filed my taxes for the first time and trying to figure out whats going on with my refund. Can someone explain what these cycles are about and how to find mine? I'm looking at my Account Transcript from the IRS and it shows all these codes and cycle numbers that I don't understand. Here's what my transcript shows: Internal Revenue Service United States Department of the Treasury Request Date: 02-04-2025 Response Date: 02-04-2025 Account Transcript FORM NUMBER: 1040 TAX PERIOD: Dec. 31, 2024 ACCOUNT BALANCE: -$9,502.00 ACCRUED INTEREST: 0.00 AS OF: Feb. 17, 2025 ACCRUED PENALTY: 0.00 AS OF: Feb. 17, 2025 ACCOUNT BALANCE PLUS ACCRUALS (this is not a payoff amount): -$9,502.00 INFORMATION FROM THE RETURN OR AS ADJUSTED EXEMPTIONS: 04 FILING STATUS: Single ADJUSTED GROSS INCOME: $19,216.00 TAXABLE INCOME: $3,893.00 TAX PER RETURN: $2,685.00 SE TAXABLE INCOME TAXPAYER: $12,017.00 SE TAXABLE INCOME SPOUSE: 0.00 TOTAL SELF EMPLOYMENT TAX: $2,685.00 RETURN DUE DATE OR RETURN RECEIVED DATE (WHICHEVER IS LATER) Apr. 15, 2025 PROCESSING DATE: Feb. 24, 2025 TRANSACTIONS CODE EXPLANATION OF TRANSACTION CYCLE DATE AMOUNT 150 Tax return filed 20250602 02-24-2025 $2,685.00 30221-424-22060-5 766 Credit to your account 04-16-2025 -$3,357.00 768 Earned income credit 04-17-2025 -$8,830.00 I see there's this "CYCLE" column with the number 20250602 next to my tax return filed line. Is this my cycle code? And there's that number 30221-424-22060-5 below it. What do these numbers mean and how do I use them to track my refund? Also, what's the difference between the "Credit to your account" and "Earned income credit" lines? My total refund looks like it should be $9,502.00, but I'm not sure when I'll actually get it.
