That's exactly what you will be doing whether you do it now or later.
If you do it now, you can take advantage of e-File of 1040-X which lasts until Oct 15th.
"(roughly $600)"
not good enough, you must enter the exact amount of positive earnings.
You can get that by subtracting your contribution from the amount the custodian returned to you.
If you get the correct result on Form 1040, it doesn't really matter what 1099-R box 7 codes you use.
