Ive tried multiple online tools to resize my screenshots for the 4.7-inch and 5.5-inch formats at 1334 x 750 and 2208 x 1242 respectively. For some reason the largest I am able to get my screenshots is 1136 x 640? That is the original size of the screenshot I am using. Is there any way to modify the image and make them larger than the original to have them fit the appropriate settings?
App store 4.7 inch and 5.5 inch screenshots?? How do I get them?
Install the app on those devices and take the screen shots. If you don't have those
devices, load your app in xCode and run it in the appropriate simulator for each
size and take the screen shots. Up sampling an image is never a good idea but
if you absolutely must do this, any decent graphics editor, even preview can perform
this change with ease.
The following resolutions are acceptable to iTunes connect:

iPhone 5, iPhone 5S, iPhone 5C (4 Inch) 640 x 1136

iPhone 6 Plus, iPhone 6S Plus, iPhone 7 Plus, iPhone 8 Plus (5.5 Inch) 1242 x 2208
You need the screenshot in this resolution, the phone scales them down to 1080 x 1920

Hope this helps. Even Apple's Documentation on the matter is incomplete. Update: Apple has introduced a new Media Manager which requires only that you create artwork for the largest iPhone and/or iPad devices. The smaller images will be created for you. Note that if you hadn't been creating iPad Pro images before, you have to now (if you support iPad).
