Classification starts with where the money went and how fast. A tax-free reinvestment from one qualified plan into another plan or the same plan is a rollover. Generally, the rollover must be completed within 60 days of receiving the distribution, and the IRS may waive the 60-day requirement where missing it would be against equity or good conscience. The payment method changes withholding: an eligible rollover distribution paid to the participant generally carries 20% withholding, while no tax is withheld when the administrator pays it directly to the other plan or IRA. Not every payment is eligible for rollover: required distributions are not eligible for rollover treatment, and the exceptions to eligible-rollover treatment include a hardship distribution, among other listed payments.
Only one IRA-to-IRA rollover is allowed in any 1-year period no matter how many IRAs are owned; trustee-to-trustee transfers between IRAs and traditional-to-Roth conversions are not limited.
Amounts not rolled over keep their character: pre-tax money included in income, after-tax money treated as basis as IRA Basis and Roth Treatment explains.
Report it as follows: the total distribution is entered on Form 1040 line 5a as shown in box 1 of Form 1099-R; after-tax contributions usually shown in box 5 are subtracted, then any amount rolled over directly or within 60 days, and the remainder — even if zero — is entered on line 5b. A direct rollover is marked with code G.

Worked example
Tina's $20,000 401(k) distribution is paid to her on March 1. Because the check comes to her, the plan withholds 20%, $4,000, and sends a $16,000 check. On March 31 she deposits $20,000 into a traditional IRA: the $16,000 plus $4,000 of her own savings to replace what was withheld. The reinvestment lands inside 60 days, so the full $20,000 is a rollover, nothing stays in income, and the $4,000 withheld is credited as tax paid on her return. Had she deposited only the $16,000, the $4,000 she did not roll over would be taxable. Had she instead asked for a direct administrator-to-IRA payment, no withholding would have applied at all.
