You have to attach a copy of I-130 receipt letter to the I-129F package for K-3 and send the I-129F to the service center indicated on the I-130 receipt letter.
Keep in mind, for most CR-1 only takes a month or so longer to process than K-3. CR-1 costs much less overall. CR-1 is a true immigrant visa that results in a green-card upon entry to the USA K-3 needs to file I-485 to adjust status ($1010), K-3 also cannot work, get SSN, or a driver's license until they have green-card or EAD. EAD can take 90 days or more to get.
Compare timelines to get an idea if the time difference.
USCIS has been holding the I-130 back once you file I-129F for the K-3. So the decision to go CR-1 or K-3 needs to be made BEFORE sending in the I-129F

After so many months, it seems like a broken record but filing an I-129F for K3 is no longer an automatic no brainer choice. If you check the full timelines from filing to visa for your Consulate and compare CR1 to K3, you'll be able to make a more informed decision. You would also want to weigh your priorities regarding speed to visa and speed to working in the US. Some people would rather wait a couple months longer apart and avoid both the extra expense of adjusting status and the minimum of 3 or 4 months without authorization to work.
Later, if you wish you could get a CR1 visa, you'll be very sorry your filed the I-129F. Weigh those options carefully.
The direct answer to your question is that the letter they sent you is the notice of action you need to file the I-129F. If you decide to do so, include a copy with your petition filing.
