This was not a loan from your IRA because IRAs are not permitted to make loans. Instead, this was a distribution and rollover from your IRA.
Enter the Form 1099-R under Wages & Income -> Retirement Plans and Social Security -> IRA, 401(k), Pension Plan Withdrawals (1099R). In the follow-up, indicate that you moved the money to another retirement account (or back to the same account) and indicate the amount that you rolled over.
