If you're worried about the $5 that's just earnings in the IRA which is sometimes unavoidable, you'll pay a little tax on the $5 part of the conversion.
As long as the $7000 was a valid non-deductible contribution then you should be fine. A common reason for it to not be valid is it you don't have any "earned" income like a W2, say in retirement, you cannot contribute more to any Trad or Roth IRA than you have earned income.
When you do your taxes you'll input this in 2 parts; the non-deductible IRA contribution in the Retirements section under Deductions, and you'll get a 1099-R for the conversion which you'll input under the Retirements section under Income. When you do the 1099-R input there will be some questions about what you did with the money which you need to answer carefully, see help page below. The contribution and tax on the conversion will be calculated on Form 8606.
You'll eventually get a 5498 showing the contribution but those usually don't go out until May as IRA contributions for prior tax year can happen up until April 15th, but you don't need that form to file.
