I’d suggest locating the center of your heat spreader and applying any leftover thermal paste there. Once the heatsink is back in place, the paste should spread uniformly. Capture a photo with your phone or webcam and share it here for better assessment of your application. If you don’t have thermal paste, just reinstall the cooler and use Open Hardware Monitor to check temperatures.
It wasn't ideal to apply the thermal paste as recommended for lasting use; it might have worked briefly if you avoided heavy loads. A thermal pad could be a better choice since it applies more evenly and stays stable over time.

Typically you desire a small amount in the center, slightly bigger than a pea. I believe this could be a bit excessive...
Stay calm and monitor the situation. If temperatures rise by around 10 degrees in a month, consider reapplying, though it’s okay if it looks normal.
Keep an eye on the temperatures—it should be okay right now. The amount you used might just be sufficient. Usually, you don’t want to put the paste too close to the chip’s edge so it doesn’t leak and cause a mess, which could even drop into your CPU socket. For the Ryzen, the pattern works well, but next time try keeping it shorter on the X side. A half-length line would be ideal. What most people assume isn’t enough is still double what you actually require.
