text-decoration: none;

You just need to change your left: -340px; to right: -340px; and then your transform: translateX(340px); to transform: translateX(-340px);. Both of these are within the media query.
Here's a working example (if you view in full screen and scale the window width down to preview):
/* grid */
.container {
display: grid;
grid-template-columns: 1fr;
grid-gap: 10px;
}
/* items */
.container > * {
color: #353535;
font-size: 1.2em;
line-height: 1.5;
padding: 20px;
background: #d0cfc5;
}
/* nav styles */
.container nav {
background: #136fd2;
}
nav ul {
list-style: none;
margin: 0;
padding: 0;
}
nav a {
color: #d0cfc5
}
nav a:hover {
text-decoration: none;
}
/* media query for grid layout */
#media only screen and (min-width: 600px) {
/* grid */
.container {
grid-template-columns: repeat(4, 1fr);
}
/* specific item styles */
.container header,
.container nav,
.container footer {
grid-column: span 4;
}
.container section {
grid-column: span 3;
}
/* nav styles */
nav ul li {
display: inline-block;
padding: 0 20px 0 0;
}
/* hide toggle */
.toggle {
display: none;
}
}
/* media query for nav styles */
#media only screen and (max-width: 599px) {
#nav {
transition: transform .3s ease-in-out;
top: 0;
bottom: 0;
position: fixed;
width: 300px;
right: -340px;
}
#nav:target {
transform: translateX(-340px);
}
.close {
text-align: right;
display: block;
text-decoration: none;
font-size: 3em;
position: relative;
top: -30px;
}
.open {
text-align: left;
}
}
